CHU'IE FOR FILLING-REPLENISHING LOOMS.

menses.

Be it known that I, CARL D. BROWN, a citizen of the UnitedStates,'residing atHopedale. county of Worcester, State ofMassachusetts, have inventedan Improvement in hutes for Filling-Replenishing Looms, of wh ch the following description, inconnection with the accompanying drawing, is a specification, likecharacters on the drawing representing like parts.

This invention relates to weft replenishing looms preferably of theautomatic type and its object is to provide means for catching 'andthusretaining the trailing end of the abandoned filling carrier after it isd scharged from the shuttle .in. the operation of replenishment so thatit will not be caught and'carried by the shuttle ortlte fresh fillingcarrier-into the cloth upon the succeeding -iclr. r I

This object is secured in the present invention by providing the chutewhich guides the discharging filling carrier with means for ca tchingand retaining the trailing filling end preferably by serrating the upperedge of the chute. 4

l The object also is to provide a chute capable of yielding bothforwardly and rearwardly so that danger of breakage or of a smash isprevented if the filling carrier be caught between the chute and amoving part of the loom during its discharge and at the same time toprovide means for insuring that the yielding chute shall always returnto a definite normal position.

Theseand other objects of the invention will appear more fully from theaccompanying description and drawings and will be particularly pointedout in the claims.

ing a slightly different form of construction;

Fig. 6 is a view similarto Fig. construction shown in Fig". 5.

The present invention is not concerned with the particular constructionor operation of the general features of the loom to which it is applied.For convenience of illustration the invention is shown in the 4 of thepreferred form selectedas' embodied in an automatic filling replenishingloom of the well known Northrop type.

In this type of loom the frame or loom side 1 supports at-the transferend of the loom a hopper stand 2 upon which is mounted a rotary hopper 3carrying the supply of fresh filling carriers 4. The lay 5 carries atthe transfer end the shuttle box 6 and the lay and shuttle box areprovided with a vertical opening 7 therethrough to permit the downwarddischarge of an abandoned filling carrier when the shuttle 8 is boxed atthe transfer end of the loom. A transferrer 9 is pivotally mounted onthe hopper stand and provided with a dog 10 avhich upon the call forfilling replenishthus causing the transcase a bobbin 4. from the hopper3 into the shuttle-8 and thereby discharge the abandon'ed or exhaustedfilling carrier or bobbin in the shuttle down through the opening 7.

The end of the filling extending from the abandoned filling carrierthrough the eye of the shuttle is usually. in feeler looms, severed bysuitable mechanism adjacent the nose of the shuttle and this severed endmust be drawn back through the eye of the shuttle and clear of theshuttle or it is liable to be caught by the shuttle or by the freshlling carrier and dragged back into the shed and woven into the clothcausing an imperfection.

In the construction therein illustrated the discharging filling carrierthrough the opening 7 is guided by an end guide and a plate or chuteclear of the working parts of the loom and falls into a suitablereceiver or bobbin box placed on the floor beneath.

IlpOIl passlng v forwar- The end guine 12 may be of any suitableconstruction such as the late shown with a y projecting edge ant.supported by a braclt t 13 depending beneath the lay and acts topreventthe filling carrier from endwise movement toward the body of theloom.

The chute comprises a flat guiding plate 1% journaled on a suitablesupport herein shown as a bracket 15 projecting from and carried by theloom side 1. This bracket carries a laterally extending; journal pin 16.The chute plate is is secured by rivets or screws 17 to a base plate 18provided at its ends with downwardly projecting bearing lugs 19, 20.'ihese lugs are apertured to provide bearings fitting over the journalpin 16 and these bearing apertures are slightly larger than the pin 16,the one 21 at the right being efer-ably elongated as shown in the drawrug. T he chute supporting bracket 15 is provided with a positioningsurface which in the construction shown in Figs. 3 and i is a flatsurface 22 formed on the top of the upstanding portion of the bracketand the chute is provided with a corresponding chute position definingsurface which in the construction shown in Figs. 3 and l is a corresponding fiat surface formed on the. bottom of a lateral projection 23 fromthe lug 20. A helical spring 2& connected to the lower p01- tion of thelug and to a projection 25 from the chute supporting bracket 15 acts tohold these chute positioning surfaces in contact and thus cause thechute to be maintained in normal position. This spring; preferablyextends in line with the journal axis and norreal to the contactingsurfaces which sur- "faces extend preferably parallel with the journalaxis.

lhe normal position of the chute is preferably about as illustratedinthe drawings and is such that when the lay heats up the chute standinga rearward inclination ust tacts at its upper edge with the rear wall 1U .g 2 so that the discharged i'ill inn carrier forced out through theopening slides down and is guided by the chute into ual receiver orreceptacle placed beneath the hopper. is dificult to obtain this preciserelation of the chute and rear wall of the opening; in practice owing tothe wear which takes place in the loom parts,

liculty or" accurate adjustment liability for the lay to overthrowslightly, and hence tie chute is made to yield forwardly and thus rockon its journal with the lay so as to maintain at all times its upperedge in contact with the wall '2'. This construction also prevents anydanger of a smash occurring if by chance a filling carrier in itsdischarge in some gets behind, the edge of the chute.

in order that the trailing end of the l i w ill the shuttle or the andthe.

a nee-aces pointing on its return movement after transfer the trailingend of the filling is caught over this so rated edge and is caught andretained thereby s0 that it cannot be carried back by fresh fillingcarrier into the shed.

if the filling carrier in descending on the chute should'be caught by amovin part of the loom such for example as the hunter 11 while the laywas moving rearwardly it might get wedged in against the chute 1e andbreak or injure the chute and this not infrequently happens. lio preventthis the means described permits the chute to yield rearwardly.

Whenever the means which causes the chute to yield or pivot in eitherdirection ceases to act the spring 24: immediately restores the chute tonormal position defined by the contacting positioning surfaces and thusform its functions. It will be seen that as the chute is rocked or swungin either direction the positioning surfaces separate and the chute iscammed out of normal position by the corners of the upstanding portionof the bracket 15.- This camming action requires that the chute shall beloosely journaled and also that'the bearingat the right hand end shallbe slightly elongated as illustrated.

It is obvious that the positioning surfaces may be variously disposedand variously shaped the only requirement being that they shall be soshaped and'positioned as immediately to restore the chute to its normalposition under the action of the spring when the deflecting force hasbeen removed.

in Figs. 5 and 6 another form of construction embodying the invention isillustrated. in this construction the upstanding portion 27 of the chutesupporting bracket is extended horizontally at its top and the journalpin 28 projects laterally from the rearward portion thereof. The bearinglugs 29 and 30 extend forwardly from the bottom of the chute andthe-positioning surfaces are formed by the vertical contacting suriacesof the lug 30 and upstanding portion 27 of the chute supporting bracket.Consequently, also, the helical spring 31 is arranged horizontally. Itwill be seen that the functioning of the parts is, however, very similarto that shown in Figs. 3 and 4.

Having fully described my invention, what i claim as new and desire tosecure by Letters Patent is:

i. a wei't replenishing loom, a lay provided with a shuttle box andhaving an opening therethrough to permit the discharge of the abandonedfilling carrier, a chute support mounted on the loom frame, a chuteiourialed in said support extending upthersirom and acting to receiveand toward the right. As the lay starts the chute is always in positionto permemes guide the discharged filling carrier, means actin to permitthe chute to swing yieldingl both forwardly to insure contact with thelay on the heat up and to prevent a sinasl if the discharging fillingcarrier passes behind the chute and rearwardl to prevent a smash it thedischarging filling rarricr is caughtbetn'cen the chute and a movingpart of the loom, contacting sur faces on the clu te and chute supportacting to maintain the chute in normal positioin and means acting torestore the chute to normal position with said surfaces in contact whenthe chute is swung in cit-her dircction,
